SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 268,909, dated December 12, 1882.

Application filed June 19, 1882. (No model.)

To all whom it may concern:

Be it known that I, KARL SIGURD KLocEL, of Wardsberg and Backestad, near Linkoping, Sweden, have invented a new and Improved Sewing-Machine, of which the following is a full, clear, and exact description.

The invention consists in combining with a shuttle-track a rotary carrier on the end of the main shaft, a hinged flap, and a slide; also, in combining with the cloth-feeder certain par-ts, all as hereinafter described.

iet'erencc is to be had to the accompanying drawings, forming part of this specification, in

I which similar letters of reference indicate corshuttle.

responding parts in all the figures.

Figure 1 is alongitudinal elevation of myimproved sewing-machine, showing parts in section. Fig. 2 is an end elevation of the same, showing parts in section. Fig. 3 is a plan view of the needle-hole plate. Fig. 4 is a longitudinal elevation of the same. Fig. 5 is a plan view of the presser-foot. Fig. 6 is a plan view of the shuttle-path. Fig. 7 is a plan view of the Fig. Sis a longitudinal sectional elevation of the same. Fig. 9 is a longitudinal elevation of the cloth-feeder. Fig. 10 isa plan view of the same. Fig. 11 shows the hook for removing the shuttle in front and-side view. Fig. 12 is a plan view of the shuttle-carrier.

The arm A is fastened on the machine-plate B, and the toremost part or head 0 of the arm' is made of a separate piece and is attached to this arm. The front plate, D, which covers the head 0 contains the grooves in which the needle-bar E and the presse-r-foot bar F move up and down. The main shaftGisjournaled horizontally below the plate B, and is provided at one end with a grooved pulley, G, for a driving-belt, and with a fly-wheel, G This flywheel G has a crank-arm, H, which by means of the connecting-rod I and the crank-piece J on the end of the upper shaft, K, in the arm A gives this shaft K an oscillating movement.

At its end in the head D this shaft K is proarm A and passes through a vertical slot, 0, in the needle-bar E, and is moved up and down by this needle-bar. A spring. P, is attached to the end of the inner arm of thetake-up O, and the other end of this spring is attached to the arm A. This spring draws the outer end of the take-up upward. The tension deviceQ for the upper thread is secured on the front plate, D, and consists of two rubber disks or shives, which are pressed together by a nut, the thread passing between these two rubber disks or packings. The presser-foot bar Fis pressed down by a spiral spring, It, the lower end of which is fixed to the front plate, D, and the upper end of which is fixed to a small slide, S, held in the presser-bar. This slide projects from the upper end of the presser-bar and 'is provided with a nut, S, by means of which it can be raised or lowered on the presser-bar, and the tension of the spring R can thus be adjusted. An arm, T, is attached to the presser-bar F, and rests on the inner end of'a camlever, U, pivoted to the inner surface of the front plate, D, by means of which camlever U the presser-bar and presser-foot can be raised. The presser-foot bar is also provided with a button, W, whereby the presser-foot can be held raised by hand. The lower endof the presser-bar is provided with a tenon which fits into the mortise in the presser-t'oot V, and

which foot V isheld to the lower end of the presser-bar by a suitable screw, as shown in Figs. 2 and 5. The lower end of the needlebar E is provided with an obliqueaperture a, through which the upper thread is passed before it is passed through the eye of the needle. The stitch-plate or sewing-plate b is provided with a small piece,c, havingan aperture through which the needle passes, so that in case this piece becomes worn by having its edges chipped off by the needle when the same does not move accurately this piece 0 can easily be removed and replaced by another without removing the entire sewing-plate. The shuttlepath 0} is fixed to the under side of the machineplate B, and is provided on its right-hand side with a flap e, which can be turned around the screw f. When the machine is in operation this flap is'held in its proper position by the slide g, which rests upon the upper straight edge of this flap, and thus prevents further movement ofthe flap. If this slide 9 is drawn out the flap ecan be turned down, and the shuttle It can easily be removed by means of the book i, which is passed in the aperture h at the front end of the shuttle. The threadis led into the shuttle in the usual way-in and out several times throughapertures in the side of the shuttle--and is then passed through the above-mentioned aperture It. At its rear end the shuttle is provided with a hook-projection,j, which catches in an aperture in the shuttle-carrier k, which carrier rotates the shuttle with it when the machine is in operation. The shuttle-carrier It has the form of a book, one end of which is attached to the end of the main driving-shalt G, and in the free end of this hook-shaped receptacle or shuttle-carrier It the shuttle h is placed, as is shown in Fig. 2. The shuttle is held in the shuttle-carrier in such a manner that it will pass through the loop of the upper thread very easily. When the shuttle moves the lower thread passes through the loop above the shuttle-carrier, and is from there drawn up by the upper thread, as usual. The cloth-feeder is contained in a grooved track between the ma chine-plate and the shuttle-path. It consists of a head-piece, l, and the angle or elbow lever m, which is fastened to the head-piece by means of a screw in such a manner that. it can be turned; or, in other words, it is pivoted to the head-piece l. The head-piece l is provided with the usual feeder-teeth, l, as shown in Figs. 9 and 10, and with a downwardprojecting foot, Z, which rests on the eccentric n on the main shaft G. One arm of the lever m rests on the eccentric 0, also mounted on the main shaft. G. The other arm of the angle-lever on rests against one end of the straight lever 11, which is pivoted at q, Fig. 1. Thefront end of this lever 19 passes intoa groove between the front b aring of the main shaft G and a lug, r, projecting from the under side of the plate A, and through the inner end of this lever 19 a screw, 8, passes, by means of which this inner end can be lowered and raised, and thus the outer end of the lever 19 can be adjusted higher or lower along the down wardly-projeoting shank or arm of. the angle-lever m. By the co-operation of the eccentrics n and o, the angle-lever m, and the lever 21, the feeder must reciprocate horizontally, and this to a greater or less degree accordingly as the free end of the lever 17 is adjusted to be a greater or less distance from the pivot of the angle-lever m. The length of the stitch can thus be regulated very conveniently by means of the screw 8. A spring, t, presses on the feeder mechanism, and holds the same on the eccentrics n and 0. The stitch-plate b is provided on the under side with a recess or concavity, 1), into which the sh uttle-carrier can pass in its rotation. The head 0 is provided with a swinging side, t, Whichcan beopened if part of the mechanism in the head is to be examined.

The operation of this machine is very similar to that of other sewing-machines in which a rotary shuttle-carrier is used.

' Having thus fully described my invention, I

claim as new and desire to secure by Letters Patent 1. A sewing-machine cloth-feeder consisting of the head-piece l l, with foot 1, and the le ver m, pivoted thereto, in combination with shaft Gr, having an eccentric, n, which supports the foot, and an eccentric, 0, which supports one arm of said lever, the lever 11, supporting the other arm of lever 1n, and passing into a groove between the front bearing of shaft A, the plate-lug r, and the screw 8, as and for the purpose specified.

2. In a sewing-machine, the combination, with the shuttle path or track 01 of the rotary shuttle-carrier 70, attached to the end of the shaft G, of the hinged flap e and the slide 9, substantially as herein shown and described, and for the purpose set forth.
